Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 24/9-14 S was drilled on the Froskelår injectite sands in the Vana Sub-basin in the North Sea. The structure was first drilled by 24/9-3 in 1981 and oil was discovered in the Frigg Formation. These Frigg sands were later re-defined as injectites. The objective of wildcat well 24/9-14 S was to appraise petroleum and reservoir potential in these sands (Eocene Intra Hordaland group sandstones).

Operations and results

Appraisal well 24/9-14 S was spudded with the semi-submersible installation Scarabeo 8 on 19 January 2019 and drilled to TD at 2286 m in the Paleocene Sele Formation. Operations proceeded without significant problems. Oil and gas were discovered, and a coring and data acquisition side-track 24/9-14 ST2 was drilled after reaching TD in the main well. The side-track was drilled from kick-off at 1812 m (1657 m TVD) to its TD at 2145 m (1955 m TVD). The well was drilled with Seawater and sweeps down to 218 m, with KCl/Polymer/GEM mud from 218 to 1558 m, and with Innovert oil-based mud from 1558 m to TD. The side-track was drilled with Innovert oil-based mud from kick-off to its TD.

With reference to the main bore: top of the injectite complex was encountered at 1887 m (1732 m TVD) with a main injectite sand in the lower half from 1936 to 1953 m (1781 to 1798 m TVD). There was gas with a gas-oil contact at ca 1763 m TVD and oil with a down-to contact at the base of the main injectite at 1798 m TVD. From pressure data the OWC is placed at 1838 m TVD. Further, pressure data indicate the same oil and water gradients in 24/9-14 S as in the 24/9-3 discovery well, only ca 2.5 bar depleted. This is consistent with production-depletion from the near-by Bøyla Field. Due to OBM-masking of shows on cuttings oil shows are describe

About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
